Mali covers 1,240,192 km² (478,841 sq mi), which makes it the eighth-largest country in Africa and about the 23rd-largest in the world. It is almost exactly the size of South Africa, nearly twice the size of France and about 1.8 times the size of Texas. The country is landlocked and spans about 15 degrees of latitude, from savanna on the southern border near 10° N to Saharan desert near 25° N. A trip from the capital Bamako to the salt mines of Taoudenni covers roughly 1,200 km in a straight line, and most of the northern half has very few people.
Mali lies between latitudes 10° and 25° N and longitudes 13° W and 5° E, in the bend of West Africa where the Sahara meets the Sahel. Seven countries surround it, and its land borders add up to 7,243 km: Mauritania (2,237 km) to the west and north-west, Algeria (1,376 km) to the north-east, Niger (821 km) to the east, Burkina Faso (1,000 km) to the south-east, Côte d'Ivoire (532 km) to the south, Guinea (858 km) to the south-west, and Senegal (419 km) to the west. Our guide to the countries that border Mali goes through each frontier in turn.
Bamako, on the Niger in the south-west, is the natural starting point. More than 90% of Malians live in the southern part of the country, and the capital alone has over 4 million residents. Measured from Bamako, the rest of Mali stretches surprisingly far.
North From Bamako to Taoudenni: 1,200 km From Savanna to Salt Flats
Heading north, the journey crosses all three of Mali's natural zones. The southern Sudanian zone around Bamako and Sikasso is cultivated savanna with a rainy season from late April to early October. Further north the centre of the country is the semi-arid Sahel, with a long dry season and a short, irregular rainy season. North of the Niger bend lies the Saharan zone, which has a hot desert climate where rain is rare and grows rarer the further north you go. Desert or semi-desert covers about 65% of Mali.
Timbuktu, about 700 km from Bamako, sits near the river at the edge of the sand. Taoudenni is another 664 km north of Timbuktu, deep in the desert. It is the capital of the new Taoudénit Region, although the regional administration works from Timbuktu because Taoudenni lacks the infrastructure. Salt is still dug by hand from an ancient lake bed there, cut into slabs and carried south by truck or camel; the azalai caravans are among the last still working in the Sahara.
This northern extreme is also the hottest part of the country. Average highs reach about 46 °C in June at Araouane, between Timbuktu and Taoudenni, and close to 48 °C in the Taoudenni area in July. Sunshine there totals around 3,600 to 3,700 hours a year. These were the stops on the old trans-Saharan trade routes, and the length of the desert crossing explains why Timbuktu grew rich as the point where camels met river boats.
West to East: Kayes on the Senegal to Ménaka Near Niger
Mali is nearly as wide as it is long. Kayes, on the Senegal River in the far west, is about 420 km north-west of Bamako. With April highs averaging about 44 °C, it is nicknamed the pressure cooker of Africa. From Kayes to Ménaka, the regional capital close to the Niger border in the east, the straight-line distance is about 1,490 km, and from Kayes to Gao it is about 1,240 km.
All of this runs on one clock. Mali uses Greenwich Mean Time (UTC+00:00) throughout the year with no daylight saving. Because the country spans 18 degrees of longitude, solar noon in Ménaka, almost 14 degrees east of Kayes, comes about 55 minutes earlier than in Kayes, although both towns read the same time.
The far west also holds the country's lowest point, 23 m above sea level on the Senegal River. The north-east rises into the Adrar des Ifoghas, a granite massif in the Kidal Region that continues into Algeria and covers around 250,000 km² of wide valleys and eroded boulder hills, with Kidal, Aguel'hoc and Tessalit among its settlements. Kidal is about 1,200 km from Bamako and some 290 km north-east of Gao.
The west–east crossing also spans a geological seam. Western Mali sits on the ancient West African craton, while the south-east rests on the Tuareg shield; the two blocks joined between 600 and 550 million years ago, and the line where they meet runs just west of the Adrar des Ifoghas. Much of the north-west is covered by the sediments of the Taoudeni basin, while older crystalline rock comes to the surface in the south-west around Kéniéba and Bougouni, two outcrops that hold valuable mineral deposits.
Following the Niger's 1,693 km Arc Through Mopti, Timbuktu and Gao
The single feature that ties Mali together is the Niger River. Of its 4,180 km course, 1,693 km run through Mali. It enters from Guinea in the south-west, flows north-east past Bamako and Ségou, spreads into the Inner Niger Delta, swings east near Timbuktu and then turns south-east past Gao towards Niger. The river provides drinking water, fish, irrigation and, for much of the year, a transport route.
The Inner Niger Delta, also called the Macina, is a region about 400 km long between the Niger and its tributary the Bani, around the river port of Mopti and the town of Djenné. In the wet season, generally June to September, the floodplain turns into a vast lake and naturally waters rice and pasture. In the dry season it shrinks back to a network of channels and lakes. From Mopti to Timbuktu is about 280 km in a straight line, and from Timbuktu downstream to Gao another 320 km. We trace the full course of the river in our complete guide to the Niger.
East of the delta, the Bandiagara Escarpment, a sandstone cliff about 150 km long that rises some 500 m above the plain, runs through Dogon country and was listed by UNESCO in 1989. The chain of cliffs ends at Hombori Tondo, whose flat-topped summit is Mali's highest point at 1,155 m. Its plateau is only about 2 km² in area, but cut off by sheer cliffs and free of grazing animals, it supports around 150 plant species.
Nineteen Regions: How Mali's 1,240,192 km² Is Divided
Mali's administrative map shows clearly where the space and the people are. Until 2016 the country had eight regions plus the Bamako capital district. Taoudénit, split from Tombouctou, and Ménaka, split from Gao, began operating that year, and in 2023 nine more were added, giving 19 regions plus Bamako.
The northern regions are huge. Taoudénit covers about 292,000 km², Tombouctou about 206,000 km², Kidal about 151,430 km², Gao about 94,846 km² and Ménaka about 78,100 km². Together that is roughly 822,000 km², about two-thirds of the country. In the 2022 census results these five regions held about 2.2 million people, under a tenth of the national total of about 22.4 million. Kidal Region had just 83,192 residents and Taoudénit 100,358. In the south, Ségou Region alone had about 2.46 million people on 52,100 km², and the smallest region, Dioila, covers only 12,330 km².
Across the whole country the average is about 18 people per km², but that figure means little on the ground: fertile southern districts are busy farmland, while the far north is largely empty. Land use follows the same split. Only about 5.6% of Mali's area was classed as arable land in 2011, and irrigated land amounted to just 2,358 km² in 2003, much of it along the Niger. Since 2012 much of the north has also been affected by the Mali War, which began with a Tuareg rebellion and drew in several armed groups. Government forces retook Kidal in November 2023, but after a coordinated offensive by the Azawad Liberation Front and JNIM from April 2026 they withdrew again from Kidal, Aguelhok and Tessalit. Large distances and limited roads continue to make the north hard to govern.
Comparing Mali With South Africa, France, Niger and Texas
Next to other countries, Mali measures up as follows:
- South Africa (1,219,090 km²) is only about 21,000 km² smaller, which puts the two next to each other in the world ranking.
- France (643,801 km², counting its overseas regions) fits into Mali about 1.9 times, a reminder of how much land France held in the colony of French Sudan before independence in 1960.
- Texas (695,662 km²) and California (423,970 km²) together cover about 1,119,600 km², roughly 120,000 km² less than Mali.
- Mali could hold the United Kingdom (244,376 km²) about five times over.
- Niger (1,267,000 km²) and Angola (1,246,700 km²) are only slightly larger, and Chad (1,284,000 km²) only a little more so.
Rankings differ by a place depending on the source: the UN-based table of countries by area puts Mali 23rd, while some summaries list it 24th. In Africa it is consistently eighth, after Algeria, the Democratic Republic of the Congo, Sudan, Libya, Chad, Niger and Angola. For a country of this size the vital fact remains its lack of a coast: its trade has to pass through seaports in neighbouring countries such as Senegal and Côte d'Ivoire, and almost every journey across Mali's map, whether by truck, boat or camel, is measured in days rather than hours.
